- UNITED STATES OSCAR W. WENTZ, OF NEW YORK, N. Y.

WRAPPER.

Application filed April 13, 1921. Serial No. 461,030.

To all whom it may concern:

Be it known that I, OSCAR W. WENTZ, residing at New York, in the countyof New York, State of New York, have invented certain new and usefulImprovements in ,l/Vrappers; and I do hereby declare the following to bea full, clear, and exact descrip tion of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

i This invention relates to wrappers particularly adapted for inclosingnewspapers,

magazines, circulars, drawings, or other books or papers which may berolled into cylindrical form.

It is the usual practice in wrapping an article of this character for Itransmission through the mails or for other purposes to roll and thenwind tightly about it one or more convolutions of paper of sufficientstrength to resist tearing. The outer edge of the wrapper is secured tothe portion thereof immediately beneath, and the tendency of the articleto unroll adds to the security with which the wrapper is held in place.

On account of the tightness of the wrappers difliculty is usuallyexperienced in quickly and easily opening packages of this characterparticularly without the use of a knife or paper cutter for slitting thewrappers. It frequently happens that the edges of the pages of thearticle become torn or otherwise mutilated while the wrapper is beingremoved, and if a knife is employed there is danger of slitting thearticle as well as the wrapper.

Various arrangements have been proposed for overcoming the disadvantagesmentioned above such as the provision of a cord or the like which isplaced beneath the wrapper so that the latter may be severed by drawingthe cord through it from one end of the package to the other, or theprovision of a weakened line running longitudinally of the packageand'which is made by perforats ing or otherwise cutting the wrapper sothat it may be easily torn along this line. The first named arrangementadds to the cost of the wrapper, while the second arrangement may weakenthe wrapper to such an extent that it may become torn accidentallyduring transmission or by handling of the package before it reaches itsdestination.

It is an object of this invention to provide a wrapper for articleswhich may be rolled into cylindrical form, which is cut so that it maybe quickly and easily severed and removed without the use of instrumentsand which when in place will possess the strength of a continuous sheetof paper, thereby preventing any danger of the package openingaccidentally.

In accordance with the invention the wrapper-blank is provided with aplurality of parallel slits or series of perforations which are soarranged that when the wrapperis wound about a rolled article they willextend substantially at right angles to the axis of the roll thusproducing a series of transverse straplike portions of the materialintegrally connecting continuous portions thereof. These straplikeportions will ordinarily subtend a relatively small arc of thecircumference of the package and will lie flat against it untildisplaced by twisting the ends of the package in opposite directions.When this occurs the edges of these portions will be slightly raisedfrom the article and separated from each other so as to permit them tobe caught and torn by running the thumb or finger along the package.

The particular nature of the. invention as well as other objects andadvantages thereof will appear more clearly from a description ofcertain preferred embodiments as shown in the accompanying drawings inwhich,

Fig. 1 is a wrapper of one form,

Fig. 2 shows the wrapper in place upon a rolled article,

Fig. 3 is another form of wrapper that may be used, and

Fig. 4 represents another modification.

The wrapper shown in Fig. 1 consists of a blank 1 preferably of paperand provided with a plurality of parallel slits 2 between which areportions 3 adapted when the wrapper is wound about an article 4 toextend at right angles to the axis of the package as shown in Fig. 2 Theslits may be of any desired length and number and placed at any suitablepart of the blank. When the wrapper is in place the portions 3 will actas straps between the non-slit parts with which they are integral, andsince they extend circumferentially of the package they will resist thetendency of the article to unroll as much as do the. continuous parts sothat there is no danger of their giving way.

When it is desired to open the package the ends may be grasped in thehands and turned slightly in opposite ,directions. Thisg actionwillcause the portions 3 to be somewhat displaced from their normalposition flat against the article so that their edges will be raisedenough to be caught by a thumb or finger nail as it is run lengthwise ofthe package. The port-ions 3 may thus be easily torn to release thewrapper.

Instead of the simple narrow slits 2 as shown in Fig l the blank may beprovided with wider slits .5 as shown in Fig. 4, or witlraplurality 01series of perforations 6 as shown in Fig. 3.

or of'dif'ferent lengths as in-Fig. l, and, i'n'-' stead of beingarranged to lie exactly at rightangles to the axis'of the package, theymay be slightly inclined, desired; without weakening the strength of theWrapper.

The slits or perforations maybe cut into the wrappers bya die or thelike at the same time that the blanks are being cut to therequiredjsize, so that no extra operationsare, requiredand the cost ofthe wrappers not increased. 1

While the Wrapper will usually, be wound;

about the article with but one convolution "For the sake of economy, theportions 3 may be severed equally well if they lie upon a lowerconvolu'tionof the wrapper insteadof upon the article itself.

Certainpreferred embodiments of the in ventio'nhave been shown anddescribed, but

In all cases the'slits may beeither of the same length as in'jFig l Iaxis of the package'when the; wrapper is inplace.
